CONCRETE MIXER Filed April 6. 1932 2 Sheets-Sheet 2 Invenlor JamelJfra'ca,

flzwaorizw Patented F eb. 20, 1934 UNITED STATES PATENT 3 Claims.

My invention relates generally to mixers and particularly to devices formixing into usable form, mineral aggregates, and water, and the like,whereby to form building material, concrete and the like, which devicesare operable either by power or by hand.

It is an important object of my invention to provide a simple and easilyconstructed device of this character which is distinguished by low costand efiiciency in operation.

It is also an important object of my invention to simplify devices ofthis general nature, and to give them more efiicient operation andrender them capable of superior results, while reducing the effort andcost involved in the operation thereof.

Other objects and advantages of my invention will be apparent from areading of the following description, taken in connection with thedrawings, wherein for purposes of illustration 1 have shown a preferredembodiment of the invention.

In the drawings:-

Figure 1 is a general side elevational view of said preferredembodiment.

Figure 2 is a top plan View of Figure 1.

Figure 3 is a sectional elevational view from one end of Figure 1. I

Figure 4 is a horizontal sectional view through Figure 1.

Referring in detail to the drawings, wherein like numerals refer to likeparts throughout the same, the numeral 5 generally designates the mixingreceptacle and the numeral 6 generally refers to the rocker supporttherefor whereby the receptacle 5 may be given the desired rockingmotion for turning over and mixing therein a charge of concrete formingmaterials or the like and water or other fluid.

The receptacle 5 is of generally rectangular elongated box-likeformation provided with a comparatively narrow transversely elongatedopening 7 disposed centrally and intermediate the ends of the top of thereceptacle. One side of the receptacle is angularly and outwardlyexpanded as indicated at 8 and in this side there is provided a spoutstructure 9 for discharging the contents of the receptacle. The spouthas the top plan view seen in Figure 2 and is composed of convex walls10 having an upward inclination as shown in Figures 1 and 2. The upperedges of the walls of the spout slope downwardly and outwardly asindicated at 11 to a level below that of the top of the receptacle.

At each end of the container the end wall is semi-circularly curved asindicated at 12 and 13, and the side walls 14 and 15 of the recep tacleare appropriately curved and connected to the ends 12, 13 by welding orother suitable construction. The curved ends of the receptacle areprovided properly shaped andpropor tioned so that when there is aconcrete mix in the receptacle it and the ingredients thereof will bethrown toward one end thereof when the receptacle is rocked and thrownupwardly and inwardly and turned over and when the receptacle is rockedin' the opposite direction,

1 mm jgif The rocker structure 6 comprises a pair of semi-circularlycurved bars 16, 17 transversely spaced and extending at either end to apoint at either end of each longitudinal side of the receptacle near theinward terminals of the curvate portions 12, 13. Each end of the rockers16, 17 has a vertically projecting member 18, 19 and 20, 21. Thesevertical members are connected in any suitable manner to the outside ofthe longitudinal sides of the receptacle and extend thereabove asindicated in the drawings, whereby to constitute handles for manuallyrocking the device of the invention when employing it for mixingconcrete or the like, and for assisting in the tilting of the device fordischarging concrete or the like therefrom from the spout 9. i

The semi-circularly curved rockers 16, 17 may be formed of round stockand the vertical mem-,

bers 18, 19 and 20, 21 formed by flattening end portions of such roundstock.

Vertical braces 22, 23 are connected between middle portions of therockers 16, 17 and the bottom of the receptacle, and between thesebraces 22, 23 and connected thereto at upper and lower portions thereofare crossed brace bars 24 which have their ends angularly turned andsecured as indicated at 25 to the said portions of the braces 22, 23,whereby to give the rocker structure rigidity adequate for requirements.

It is important that it be understood that when the sand, cement, andwater of a typical concrete mix or the like is placed into thereceptacle through the opening 7, the mix will be properly agitated andmixed when it is caused to run alternately to one end and the other ofthe receptacle by rocking the receptacle, so that and any change orchanges may be made inmaterials and in structure and arrangement ofparts within the spirit of the invention and the scope of the subjoinedclaims.

What is claimed is: 1. A mixer of the type described comprising a closedreceptacle having a flat bottom and vertically and inwardly curved ends,and provided centrally of its top with a relatively narrow transversecharging opening extending through one side of the receptacle, adischarge spout laterally extended from said side of the receptacle andin communication with the chargingopening, rocker means for rockablysupporting the receptacle, said mixer being rockable for throwing acharge against either curved end thereof for turning over and mixing thecharge.

2. A mixer of the type described comprising a closed receptacle havingvertically and inwardly curved ends, and provided centrally of its topwith a charging opening, a discharge spout laterally extended from oneside of the receptacle and in communication with the charging opening,rocker means for rockably supporting the receptacle, said mixer beingrockable for throwing a charge against either curved end thereof forturning over and mixing the charge, said rocker means comprising a pairof curved elements having at either end an upper portion secured to theside of the receptacle, the upper portions being extended above thereceptacle and forming handles for rocking the receptacle for mixing andfor tilting the receptacle for discharging by the spout.

3. A mixer of the type described comprising a closed receptacle havingvertically and inwardly curved ends, and provided centrally of its topwith a charging opening, a' discharge spout laterally extended from oneside of the receptacle and in communication with the charging opening,rocker means for rockably supporting the receptacle said mixer beingrockable for throwing a charge against either curved end thereof forturning over and mixing the charge, said rocker means comprising a pairof curved elements having at either end an upper portion secured to theside of the receptacle, vertical braces connected between the curvedelements and the receptacle, and crossed braces secured to and betweenthe vertical braces.
